LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 503,755, dated August 22, 1893. Application filed 1mm 5,1393. Serial No. 457,355. (No model.)

To all whom it may concern:

Be it known that I, CLARENCE A. TAPLIN, of Forestville, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Lamp-Burners, of which the following is a full, clear, and

exact description,whereby any one skilled in the art can make and use the same.

The object of my invention is to provide means for removably securing a lamp chimney to a burner that shall not require especial care as to the placing of the chimney in the operation, that shall afford a stable support for the chimney and that shall be positive in operation; and a further object of my invention is to provide such a device that shall be durable, simple in operation and cheap of construction.

To this end my invention consists in providing a device having a number of holding arms presenting anumber of bearing points against the chimney, each arm being pivotally attached to the chimney support between the bearing surfaces; and it further consists in details of the several parts making up the device as a whole and in their combination, as more particularly hereinafter described and pointed out in the claims.

Referring to the drawings: Figure 1 is a view in elevation, partly in section, of a lamp burner and chimney secured thereto by means of my improved fastening device. Fig. 2 is a detail view, on enlarged scale, of a portion of a burner showing the device in edge view. Fig. 3 is a detail top view, on enlarged scale, of a holding arm and its support. Fig. 4: is a detail view, on enlarged scale, of a part of a burner and in lengthwise section of a holding arm and its support. Fig. 5 is a detail view, on enlarged scale, of a part of a lamp burner showing a difierent form of the invention. Fig. 6. is a detail view, on enlarged scale, of a part of a lamp burner showing still another form of the invention.

In the accompanying drawings illustrating my invention the letter a denotes a lamp chimney that may be patterned after any of the well known forms and that may be removably attached to the lamp burner I); this burner may be made of any desired material, preferably brass, and to it are secured the chimney holding arms 0 extending upward within the chimney and removably securing the latter to the burner. These arms 0 are made of metal, brass being preferred, as that metal has been found by experience to possess the necessary resilient qualities that secure the best results. They are of such form that the lower part c of the arm shall bear against the chimney near the bottom thereof, while the upper part c of the arm has a bearing against the chimney at a point somewhat nearer its top, preferably above the bend or base of swell when the chimney has this form. The arms are made, in the desired form, so that the top part 0 shall engage within the chimney before the bottom part c has reached a bearing therein, which will cause the arms to bear against the chimney with a yielding pressure. A result of this construction in the use of a chimney with the well. known swell is. that the more force applied to remove the chimney the greater will be the pressure of the lower end of the arm against the bottom of the chimney.

In the preferred form of the device, shown in the first four figures of the drawings the letter at denotes a pivotal support for the holding arm that is pivoted to the former at a point between the bearings of the arm upon the chimney. The support is secured to the burner at its lower end and the upper end is bent outward, recesses being cut in each edge forming a T-shaped end 01 upon which the holding arm is pivoted. This T-shaped end has preferably on its upper side-a fiat bearing surface against which the spring located on the holding arm abuts.

The holding arms 0, as before stated, are preferably made from thin spring metal and a suitable socket for the reception of the pivot is formed in the arm, as by bending the arm to the shape shown at 0 A locking slit 0 is formed in the arm to afford means of assembling the parts. The end c of the arm is bent backward upon the latter forming a spring bearing against the fiat surface of the T- shaped end or pivot d tending to hold the arm with its upper end at the inner limit of its play. A stop o is formed on this spring, preferably by punching up the metal and thus forming one side of the socket for the pivot d This construction holds the upper ends of the several arms normally inward so that number of chimney bearing surfaces and atthere is little chance of misplacing the chirn ney in the operation of affixing it to the burner, the former as it is forced into place causing the upper ends of thearms to swing outward until they bear with a yielding pressure against the sides of the chimney holding it.

firmly and securely in place.

To assemble the parts the chimney holding arm 0 is placed in a position at about right angles to the pivotal support (1, the outer T- shaped end of which is inserted in the locking slit to an extent suflicient to enable the arm to be turned to its proper position at which time the pivot slips into the socket 0' and issecurely held within said socket by" the upper end of said support between said bearing surfaces, and a spring tending to hold the upper end of the arm in position to receive the chimney base, all substantially as described.

In icombination'with a chimney seat, an arm support with one end secured to said seat means-of the stop 0 In the modified form of the device shown or hinged to .the burner, as shown at e, while in the modified form shown in Fig. 6 the arms are pivoted or hinged to the upper ends-of the of the bearing ends.

My invention has been described herein with special reference to a holding arm havthesupport may be of yielding material and the arm rigid, or both parts made rigid to a degree, in which case it would be possiblexto, rigidlysecure the arm to the suppor'tand at-.
